I am breastfeeding my 7 month old still and I’ve noticed recently that my left breast is very soft, never feels full and occasionally baby will cry whilst feeding on this breast. For the first time last week I was away from baby for 8 hours so half way through this time I expressed to keep up my supply etc... only managed to get 1oz from that breast, whilst the other breast squirted out 8oz in 5 min of expressing. Is my milk going in on my left breast? There is a noticeable size difference too.
